Well, their are a lot of "medicinal" plant extracts out their, but a lot of them don't do much more then a tomato. However, this one surtainitly sounds promissing. The test will have to be repeatable and more extensive befor any such treatment it proven enough for use in the USA, but their is good news.
The big drug producers in the US will no dought analise and reduce the extract into it's key parts. Then, thanks to genentic enginearing and the ease at which bacteria pick up new material, they will trigger the specific chemicals to be produced in mass by lab bacteria vats and theirfor spare the time, expence and liveliness of our tresured plants.
However, should this proove to be another placebo effect herb, then we have a problem if the masses go crazey for it because no one will bother to make a synthetic form.
